Furious O2 customers have slammed the mobile phone provider after being left with "shoddy" signal over the past week.

Barwell-based customers of the mobile phone giants have been left with little to no signal after the company scheduled an upgrade to the 4G service in the area.

The problems, which started on Wednesday July 1, have continued for over a week, with little improvement.

One customer, who does not wish to be named, said that she had been left "frustrated" and angry by O2 as she needed her phone to contact her daughter, who is sick in hospital.

She said: "At first I thought that my phone wasn't working, but then I came into Hinckley and I had floods of text messages.

"I've overheard people in ASDA saying that they've had problems with the service, and people in my hairdressers, and it's just not on. It seems to be across Barwell.

"I phoned customer service and they told me that it was because of planned upgrades to the 4G service in the area, yet if they knew the service would be disrupted, why have we not been informed? I feel frustrated and angry."

An O2 spokesperson apologised for the inconvenience, saying: "We can confirm that we are aware of an issue with the O2 network at Barwell.

"We apologise to our customers for the inconvenience. Our engineers and those of a third party are working to restore service as soon as possible. We are updating www.status.o2.co.uk hourly."
